Scott,Paul,
Sorry to be a PITA, but I already had the drivers in the computer, for the camera and now that I have the new USB ports in the thing, it seems that I am now back to square 1, camera no go.
But here's the real nuisance, I can't remember how on earth I got the thing to work, finally.
I remember that I d/loaded the new drivers from the BenQ site and all of a sudden the camera lept into life.
I tried this again and nothing happened (after un-installing the drivers).
Everything was going fine until the darned thing got damaged.
BTW, Scott, the new USB ports have 2 circular cables, 1 from each port socket.
